C# Best way to get folder depth for a given path?

Question

I'm working on something that requires traversing through the file system and for any given path, I need to know how 'deep' I am in the folder structure. Here's what I'm currently using:

int folderDepth = 0;
string tmpPath = startPath;

while (Directory.GetParent(tmpPath) != null) 
{
    folderDepth++;
    tmpPath = Directory.GetParent(tmpPath).FullName;
}
return folderDepth;

This works but I suspect there's a better/faster way? Much obliged for any feedback.

Answer 1

I'm more than late on this but I wanted to point out Paul Sonier's answer is probably the shortest but should be:

 Path.GetFullPath(tmpPath).Split(Path.DirectorySeparatorChar).Length;

Answer 2

If you use the members of the Path class, you can cope with localizations of the path separation character and other path-related caveats. The following code provides the depth (including the root). It's not robust to bad strings and such, but it's a start for you.

int depth = 0;
do
{
    path = Path.GetDirectoryName(path);
    Console.WriteLine(path);
    ++depth;
} while (!string.IsNullOrEmpty(path));

Console.WriteLine("Depth = " + depth.ToString());
